| Abstract: | A strains of bacterium that can degrade the xanthan gum has been isolated from soil. We analysed this xanthan-degrading bacterium in terms of the morphological characteristics, physiological and biochemical characteristics and 16S rDNA sequence. Combined with the strains of morphological characteristics, physiological and biochemical characteristics and system development analysis results, we confirmed the strains belonged to the genus Bacillus of Bacillaceae. This result layed a foundation to improve the ability of degradating strains xanthan gum for further development and the improvement of the strains of site-directed mutagenesis. |
